Abstract

Although the field of vascular tissue engineering has made tremendous advances in the past decade, several complications have yet to be overcome in order to produce biocompatible small-diameter vascular conduits with long-term patency. Stem cells and progenitor cells represent potential cell sources in the development of autologous (or allogeneic), nonthrombogenic vascular grafts with mechanical properties comparable to native blood vessel. However, a better understanding of the effects of mechanical forces on stem cells and progenitor cells is needed to properly utilize these cells for tissue engineering applications. In this chapter, we discuss the current understanding of the effects of hemodynamic forces on the differentiation and function of adult stem cells, embryonic stem cells, and progenitor cells. We also review the use of stem cells and progenitor cells in vascular graft engineering.
